Thermoelastic Interaction in a Three-Dimensional Layered Sandwich Structure

The present article investigates the thermoelastic interaction in a three-dimensional homogeneous and isotropic sandwich structure using the dual-phase-lag (DPL) model of generalized thermoelasticity. The incorporated resulting non-dimensional coupled equations are applied to a specific problem in which a sandwich layer of unidentical homogeneous and isotropic substances is subjected to time-de...

Three-dimensional structure of phosphoenolpyruvate carboxylase: a proposed mechanism for allosteric inhibition.

The crystal structure of phosphoenolpyruvate carboxylase (PEPC; EC 4. 1.1.31) has been determined by x-ray diffraction methods at 2.8-A resolution by using Escherichia coli PEPC complexed with L-aspartate, an allosteric inhibitor of all known PEPCs. The four subunits are arranged in a "dimer-of-dimers" form with respect to subunit contact, resulting in an overall square arrangement. The content...

Three-Dimensional Image of A Communicating Uterus

Recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(ART) (1). Gradually, the important role of three-dimensional (3D) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).

The structure of bovine proinsulin.

Several insulin-related substances, comprising 1 to 2% of the total protein, were isolated from commercial crystalline bovine insulin. The main components of this mixture were: the 81-residue, single chain proinsulin, two degradation products of proinsulin, termed Intermediate Forms I and II, and an insulin dimer, possibly linked by covalent bonds and apparently an artifact of the preparation. ...

Space as a Semiotic Object: A Three-Dimensional Model of Vertical Structure of Space in Calvino’s Invisible Cities

Following the “spatial turn” of the last 3 decades in humanities and social sciences and the structure of semiotic object, this research studies space as the main semiotic object of Calvino’s (1972) Invisible Cities. Significance of this application resides in examining the possibility of providing a more concrete methodology based on the integration of Zoran’s (1984) 3 vertical levels of const...
